" This invention relates to improved means for withdrawing smallquantities of medicaments from receptacles or containers and applyingthem to the body. My object has been toavoidwasteand spilling oi' themedicament and restrict-ed areas; more particularly to dental cavitiespriorto filling or stopping, or to the investing tissue and adjacentparts.

The invention consists in springing onto ably'a metal or vulcanite rodof small ,diam eter, a tip of tubular'r-esilient rubber in such aportion of reduced diameter of a length ap a manner that a portion ofthetube projects a short distance beyond the end of the'holder or stem andthatthe portion of the tube on the stem forms an air tightjoint with thelatter. The end of the stem may have proximately about half the lengthof the tubular rubber tip and said end may have one or more groovesorrecesses to afford a better grip ofth-e rubber and thus prevent itslipping ofif' when inuse;

\ In some cases Imayform the projecting portion of the rubberfltip witha swelling or extension larger quantity of the medicament to be takenup,and I'may provide an additional opening laterally in said portion of thetip.

Preterablyalso Iprovide a rigid band or clip of suitablemetal,'vulcan1te or hard rub-r her, or wood,which Wlll fit tightly overthat tubular portion of the tip on the reduced 'end of the stem so astoprevent said tip slipping'ofi when in use.

But' in order that my. invention may be more clearlycomprehended I nowrefer to the accompanyingdrawingin which Figure 1, is auperspectiveview(slightly enlarged) of a preferred shape of lIlSlJl'Ll-- ment accordingto this invention, and] Figure 2, an enlarged perspective View 7 showingthe reduced end-of the holder or stem with itsrubber tubular tipremoved.

A holder or stem 35 knurled at 4: to afiord.

to facilitate its application to forming a chamber to enable a is turneddown or reduced at 5 (see Figure .2) to form shoulder 6 against whichtip/Z abuts. This tip 7 is of resilient tubular rubber of a lengthapproximately twice the;

length of the reduced end of the-holderon which it is adapted to befirmly held when. n sprung thereon.

In use the .end holder or stem 3' with its tip 7 thereon is dipped intothe medicament and pressed hrmly against a rigid part of the containerso as to expel the air in the projecting portion of said tip 7. WVhensaid resilient-tip 7 is permitted toregain its normal shape a smallquantity of the medica i ment is drawn therein ready for applica tion toa dental cavity or other part of the body. It should be understood thatthe end of duced although it is soillustrated as preferred, for such endmay have a collarink I claim tity of inedicamentfrom a receptacle andapplying it to the body, comprising a holder or stem having a portion ofits length at one end ot reduced cross-section to form an abutment-"o1"shoulder, and aresilient tip Q adapted tobe removably sprung over, andto project from the end of the reducedportion of said holder orstem.

2. A device for withdrawing a small quan-- tity of medicament from areceptacle and as holder or stem 3 need not necessarily here provide abetter grip for LA device for withdrawing a s1na1lquan In testimonywhereof I have hereunto set i my hand.
